Mark Zuckerberg is about to go back to work after paternity leave, but he has a problem.

He can’t decide what to wear.

The Facebook founder turned to his Facebook followers to work out which T-shirt and hoodie he should wear.

He’s got lots of options for both. With T-shirts there’s the grey one, the grey one, the grey one, the grey one, the grey one, the grey one, or the grey one.

When it comes to hoodies he’s got the darker shade of grey one, the darker shade of grey one, the darker shade of grey one, the darker shade of grey one, the darker shade of grey one, the darker shade of grey one, the darker shade of grey one, the darker shade of grey one, or the darker shade of grey one.

It’s not just because he’s not a fan of fashion though.

As you’d expect, Zuckerberg has a very good reason for filling his wardrobe with identical grey T-shirts.

He has previously said that even making small decisions, such as what to wear each day, or what to have for breakfast, are taxing on the mind – and he would rather not waste energy on such trivialities.

‘I really want to clear my life to make it so that I have to make as few decisions as possible about anything except how to best serve this community,’ he said, adding that he doesn’t just wear the exact same T-shirt – he has ‘multiple same shirts.’

‘I’m in this really lucky position where I get to wake up every day and help serve more than a billion people,’ he said.

‘And I feel like I’m not doing my job if I spend any of my energy on things that are silly or frivolous about my life.’
